Abnormal vaginal discharge — for instance, fluid with an unusual odor or appearance or discharge that occurs along with itching or pain — may be a sign that something's wrong.

Most causes of abnormal vaginal discharge — such as yeast infection, bacterial vaginosis or menopause symptoms — are relatively harmless, but they can be uncomfortable.

Abnormal vaginal discharge can also be a symptom of certain sexually transmitted infections (STIs). Since these can spread to involve the uterus, ovaries and fallopian tubes, and can be passed on to sexual partners, detection and treatment of STIs is important.

Rarely, a brownish or blood-tinged vaginal discharge could be a sign of cervical cancer.

Possible causes of abnormal vaginal discharge include:

Schedule a doctor's visit if you have:

Greenish, yellowish, thick or cheesy vaginal discharge

Strong vaginal odor

Redness, itching, burning or irritation of your vagina or the area of skin that surrounds the vagina and urethra (vulva)

Bleeding or spotting unrelated to your period

For self-care at home:

Try an over-the-counter antifungal cream for a suspected yeast infection.

Use a cold compress, such as a washcloth or ice pack, to relieve itching, swelling or discomfort of the vulva.

Have your partner use a condom for a week after beginning treatment, or wait a week before having sex.
